INTERESTING FACTS ABOUT POLLUTION Approximately 1/3 of male fish in British rivers are in the process of changing sex due to pollution.

Fourteen billion pounds of garbage, mostly plastic, is dumped into the ocean every year. Over 1 million seabirds are killed by plastic waste per year. Over 100,000 sea mammals and countless fish are killed per year due to pollution. Each person in the U.S. produces about 4 pounds (2 kg) of garbage a day.
